I was referring to this one of mine. We were planning to go up the same day you took this photo, but postponed it one day due to the avy forecast. I was at Timberline 2/7 and 2/8 and watched wind slabs forming on 2/8 when it was really windy. That week had four consecutive days of great weather (Mon-Thu) and would have been perfect for something longer like Rainier.
